How do I update my phone to 2.1?Support

Okay, I'm using a Mytouch 3G with T-mobile (The one with the 3.5 mm Audio Jack) and I read in the systen info that I'm on 1.6, but 2.1 is out, and 2.2 is coming out soon.

I read through a few threads, and found that 2.2 WILL be coming to the Mytouch, but that also means that 2.1 should be on mine, and I want to get 2.1 on MyTouch.

What and how do I do it? I'd prefer it to be as simple as possible, but I am fairly technologically inclined, so don't treat me like a total noob (Former palm OS 5 junkie, I learned my way around mobile file systems)
